Researchers have achieved the next breakthrough in quantum physics

These knots of BEC, called knotty solitons, form
particle-like rings or loops that roll forward at a constant
speed without deforming.

When the BEC superfluid is first created, it's made up of a
series of points in space all having a specific orientation.
The trick of the knotting technique is to change that
orientation using very precise magnetic fields - so precise,
the scientists conducting the experiment were afraid to move at
all.

With it so far? Even if the science is difficult to grasp, the
end result is simple enough: tiny knots composed of an
interlocking series of circles that look a little like smoke
rings or doughnuts. These quantum knots are also topologically
stable, which means they can't be undone and must be broken
instead. If you think about a shoelace analogy, these
particular types of shoelaces can't be pulled apart with your
fingers, and have to be cut off with scissors instead.

The tying of the knot takes less than a thousandth of a
second, according to Möttönen's research partner, David Hall.
"After we learned how to tie the first quantum knot, we have
become rather good at it," he said. "Thus far, we have tied several hundred
such knots."

This is high-level, mind-blowing stuff, and it could be a long
time before the results trickle through to everyday life. The
researchers believe the discovery might one day help inform
the development of quantum computers, where
qubits could be braided into different types of knots depending
on the task at hand.
